Horizontal type spiral settling and filtering centrifuge

Abstract

The invention discloses a horizontal type spiral settling and filtering centrifuge which comprises a machine enclosure; a feeding pipe, an overflow and liquor discharge pipe, a filtration and liquor discharge and a solid outlet are arranged on the machine enclosure; an inner rotary drum and an outer rotary drum are arranged in the machine enclosure; a spiral blade and at least one discharge hole are arranged on the inner rotary drum; the outer rotary drum comprises a settling and concentrating region and a filtering region; a concentration and overflow hole is formed in the settling and concentrating region; and a filter screen and a filter hole are arranged in the filter region. According to the horizontal type spiral settling and filtering centrifuge disclosed by the invention, characteristics of the settling and filtering centrifuge are combined with those of the rotary drums, so that a to-be-separated solid-liquor mixture is firstly concentrated and thickened in the settling region in a separating process, and then is dehydrated and dried through the filter region, and therefore, moisture content of solid materials is reduced; and for materials with low solid content and many fine particles, the pre-concentrated fine particles flow back into mother liquor through overflow liquor, so that the purposes of thickening and removing the fine particles are achieved, and therefore, the materials reaching the filter region are dehydrated and dried easier.

Description

technical field [0001] The invention relates to a horizontal spiral sedimentation filter centrifuge. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid; the centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate the two densities in the emulsion. , and separate immiscible liquids; centrifuges can also be used to remove liquids from wet solids; using the characteristics of different sedimentation velocities of solid particles of different densities or particle sizes in liquids, some decanter centrifuges can also separate solid particles by Classification by density or particle size; while the existing horizontal decanter centrifuge cannot achieve the effect of sedimentation and filtration well, the moisture content of the solid material is high, and the purpose of thickening and removing fine particles can...
